Wood and Earth
Building with wood and clay is as old as human existence. To describe the wood loam technique, it is possible to digress into an infinite number of techniques. We therefore limit ourselves to 2 wood loam techniques, with attached photos.
Loam with wood chips
A mixture of small pieces of wood with very oily clay. Let the mixture stand for at least 1 day, then fill the finished slats and reed formwork. Let the wall dry for 6 weeks before plastering it with clay plaster or lime plaster. Wood loam is not a load-bearing construction and must always have a self-supporting wooden frame! It is also important to always build with a roof overhang of at least 1 meter and with a plinth of 40 cm high in the splash area. The “Dry Hat, Dry Foot” principle.
This building system is particularly fast and therefore relatively cheap to build.
Loam with wooden slats and branches
Saw all slats and branches to the desired length of the wall thickness. Mix the base clay with water and apply the desired consistency. Brick the wood with the base loam and straw sawdust in the center of each wooden block.
As described in the first method ‘Loam with Wood Chips’
Is this is a more complex construction method and takes time.
Wood loam has a high insulation value. With its 700 kg / m3, the walls do not let the cold through and ensure a comfortable indoor climate.
Pavilion it ‘Raathuis’ ,
As seen on the banner photo above, its name is due to its honeycomb-shaped windows and its future function as a bee palace and also a meeting location, etc. Commissioned by the Fruittuin van West, the pavilion was built with abbreviated wood based on the Cord Wood technique and the principle of ZERO WASTE.
Originally a natural construction method in which short logs are stacked crosswise in a ‘natural’ mortar mixture to build walls. This technique uses local materials at minimal cost.
Stadshout (Amsterdam) tekende voor het ontwerp en de uitvoering van de bouw, leverde hout voor het skelet, resthout voor de bouw van de muren, plus het houtzaagsel voor de samenstelling van het mortelmengsel, als extra isolatie van de leemmuren. Tierrafino leverde basisleem voor de bouw van de muren , verzorgde de uitvoering van de buitenmuren en het afstucen van de van de binnenmuren met duro leemstuc van een honingkleurige wit en oker met stro.
The walls are constructed of 2 horizontal loam dams, consisting of basic loam mixed with wood sawdust, which additionally increases the insulation value of the loam, 1 dam forms the outer wall and 1 dam forms the inner wall with wood shavings in between as insulation. Vertical wooden slats have been placed on these loam dams, on which in turn 2 loam dams have been placed, etc…..
It is a fairly simple but labour-intensive construction method. It is quickly learned and with many hands-on it goes considerably faster. The result is definitely worth it.
